When you turn on the stove and use match stick which process is going on?

When you light a match, you are initiating a chemical reaction called combustion. Combustion is a process in which a fuel (in this case, the wood in the matchstick) reacts with oxygen to produce heat and light. The following steps occur during combustion:

1. Ignition: When you strike the match against a rough surface, the friction generates heat. This heat causes the chemicals on the match head to ignite, producing a flame.

2. Fuel: The flame provides the energy needed for the wood in the matchstick to start burning. The wood is made up of cellulose, a complex carbohydrate. When cellulose is heated, it breaks down into smaller molecules, such as glucose and water. These molecules then react with oxygen to produce heat and light.

3. Oxygen: Oxygen is essential for combustion to occur. The air around us contains about 21% oxygen. When the wood in the matchstick burns, it consumes oxygen from the air.

4. Products: The products of combustion include heat, light, carbon dioxide, and water vapor. Carbon dioxide is a greenhouse gas that contributes to climate change, while water vapor is a natural part of the atmosphere.

The process of combustion is essential for many things, including cooking, heating, and transportation. However, it is important to remember that combustion can also produce harmful pollutants, such as carbon monoxide and nitrogen oxides. These pollutants can contribute to smog, acid rain, and other environmental problems.
